I first tried out the transformer as a power transformer like this:
I feed power from a VARIAC to pin 4 and 6.
It end up to 230V and the current stay as low as 13 mArms.
- Output at pin 7-8 gave 4,88 V
- All other windings gave 3,66 V

** That adds up to a 40 watt rated output transformer, with about 4000 to 5000 ohms CT primary.

Try 400 to 450VDC B+ supply and a pair of 6L6GCs, 5881s or EL34s.

KT66s would also be a good option.

Load impedances from 4 to 16 ohms seem possible.

Have fun.
